What are three types of volcanoes?
Three types of volcanoes are shield volcanoes, stratovolcanoes (composite volcanoes), and cinder cone volcanoes. Shield volcanoes have gentle slopes and are formed by low-viscosity lava, while stratovolcanoes are characterized by alternating layers of lava and ash. Cinder cone volcanoes are small, steep-sided volcanoes formed by pyroclastic material ejected during eruptions.
How is a composite volcano different from other volcanoes?
A composite volcano, also known as a stratovolcano, is characterized by its steep, conical shape and is built from alternating layers of lava flows, ash, and volcanic rocks. Unlike shield volcanoes, which have broad, gentle slopes formed primarily from fluid lava, composite volcanoes typically produce more explosive eruptions due to the viscosity of their magma. This results in a greater variety of volcanic materials being ejected, including pyroclastic flows. In contrast, cinder cone volcanoes are smaller and primarily composed of volcanic ash and debris from single eruptions.
The three types of volcanoes?
Shield volcanoes are the largest of the three types of volcanoes, built from basaltic lava flows and shaped like a gentle dome. Cinder cone volcanoes have very steep slopes and reach heights of 300 meters or less, and are made from ejected lava. Composite Cone Volcanoes are large symmetrical cones made from viscous lavas that are extruded, and they are the most violent volcanoes of the three.
Is mount shasta a shield volcano a composite or a cinder cone volcano?
Mount Shasta is considered a composite or stratovolcano due to its characteristic steep profile and alternating layers of lava flows and volcanic ash deposits. Shield volcanoes are wider and lower in profile, while cinder cone volcanoes are small, conical mounds built from ejected volcanic material.
What are the kinds of cone volcanoes?
The two main types of cone volcanoes are stratovolcanoes and cinder cone volcanoes. Stratovolcanoes are large, steep-sided volcanoes composed of layers of lava flows, ash, and volcanic rocks. Cinder cone volcanoes are smaller, symmetrical volcanoes formed from pyroclastic material ejected during eruptions.

What are three basic shapes of volcanoes?
Three basic shapes of volcanoes are shield volcanoes, which have broad and gentle slopes, stratovolcanoes (composite volcanoes), which have steep sides and are typically made of multiple layers of hardened lava, ash, and volcanic rocks, and cinder cone volcanoes, which are small and steep-sided with a crater at the summit formed from ejected volcanic fragments.
Are volcanoes made of what they erupt?
Yes, the cone is formed from the ejected material.
What are characteristics of a cinder cone?
A cinder cone volcano is constructed from pyroclastic materials ejected from a central vent. These pyroclastic materials which include lava, lahars, tuffs & welded tuffs accumulate to form the cone shape we observe in these tyoes of volcanoes. They generally have slopes ranging between 30 to 40 degrees. Cinder cones are generally small volcanoes and do not exceed 500m in height. Cinder cones erupt Andesitic lava which has a relativley high viscosity meaning it is thick and flows slowly. Because of the viscosity of the lava they erupt fairly explosivley.Cinder cones are very small and has lava that is very active and are very explosive
What is a vent in the earths crust from which lava and other materials are ejected called?
A vent in the Earth's crust from which lava and other materials are ejected is called a volcano.
Where is pumice formed?
Pumice is formed near and above volcanoes from foamy lava that has been ejected.
